Species
Nerita peloronta
Shell Type
Gastropod (univalve); Globose/Turbinate shape
Family
Neritidae (Nerite family)
Size
Approximately 0.75 to 1.25 inches (19-32mm). This specimen appears to be an average adult size.
Color & Pattern
Yellowish-white to gray base color with distinct zigzag or wavy purple-black and reddish markings. The interior (not fully visible here but known for identification) features a white parietal area with two red-stained 'teeth' that give it its name.
Rarity
Common
Habitat
Intertidal zone; found on rocky shores at or above the high-tide line (splash zone) where they cling to rocks to avoid predators and desiccation.
Geographic Range
Tropical Western Atlantic; including South Florida, the Caribbean Sea, Bermuda, and the West Indies.
Description
A thick, heavy, globose shell with a low spire and a large body whorl. The surface is sculpted with numerous flat, spiral cords. The shell is famous for its flat, white columellar deck (parietal area) which bears two prominent teeth surrounded by a blood-red or orange stain.
Key Features
Red staining around the columellar teeth; thick shell; zigzag color patterns; globose shape with a flattened base.
Collector Value
Low to Moderate ($1-$5). Highly desired by beginners for its unique 'bleeding' appearance, but very common in its range.
Condition Notes
Moderate condition. The shell shows some signs of beach wear and slight erosion of the spiral ribs, likely due to the high-energy surf environment. Collectibility grade: Fair to Good.
Interesting Facts
The 'blood' around the teeth is actually a pigment used to deter predators. These snails are highly adapted to life out of water and can survive long periods in the splash zone by sealing their operculum.
Ecological Role
Grazer; plays a vital role in controlling algal growth on coastal rocks. They are a food source for shorebirds and crabs.
Similar Species
Nerita tessellata (Checkered Nerite) which lacks the red staining, and Nerita versicolor (Four-toothed Nerite) which has more teeth and lacks the specific red 'bleeding' mark.
Beach Finding Tips
Look on large rocks and jetties in the upper intertidal zone during low tide. They are often found huddled in crevices to retain moisture.
